Gstr1 filed but arn not received - no sms - no email

You ll be check it in spam...
Also check the return dashboard once again it is filed or not...
And Check your registration details as phone number and mail ID is correct are wrong..

Not in spam. Dashboard says Filed. Registration details perfect as had Filed 3B. Had received the ARN then. Tried calling the GST helpdesk but waiting for 11 minutes twice and another time 20 minutes there was no reply. So as suggested by Tamizh vanan had taken a screenshot of the dashboard which showed GSTR1 Filed and have mailed them

Same problem with me. I had files on 4th. It was a period when GST portal was having lot of trouble. Even I am receiving similar message GSTR1 not filed, whereas postal showing filed
